For real-time data Process of digital images, all things that related to problem-domain are understood individual object and then it Is necessary to program using object oriented approach to grasp all problem as a objects operation by means of message transmission among objects. In this study, for digital photogrammetry class is designed using object oriented programming and class hierarchy is established Also, it is very useful to construct to digital photogrammetry system using class library when it is applied to close range photogrammetry.

This study aims at reviewing and analyzing the characteristics of library and information science in Korea by examming the research papers in two representative journals. In Korea, related scholarly associations have began about twenty years ago and produced a lot of research papers. For this work, I have established two aspects of knowledge system - cognitive object and subject. In this regards, the cognitive object menas the contents of research papers and the cognitive subject means the research methodology. In my opinion, this study obtains some characteristics of library and information science in Korea as follows: 1. There have been many research fields, but most of them have finished with just one or two results and not researched. 2. The adaption of information science to library science was hasty and had not the good effects in scholastic development. 3. Most research papers have been influenced by methodological prejudices. 4. In settling the native principles for the Korean phenomenon, there have been many problems. To solve these problems, I suggest that the existing research attitudes be converted to new one. I call this new research attitude 'everyday life centered research method'. Using this method, we can find the true basics and principles of library and information science in Korea.

In this paper, several problems functioning as the obstacles against software reuse were summarized. Among them, the issues dealt with in this paper include the effective method for constructing the library, the proper structure of the library, and the efficient retrieval technique. The knowledge-based approach and the information retrieval approach were integrated to construct and manage the library. The former is on the object- oriented model. Basically the object-oriented library is based on the classes and organized by inheritance. Because inheritance hierarchy is based on syntactical information, it dose not present the relationship of functionality. Using the information retrieval approach, the index file which characterizes the component and similarity among the components can be analyzed. Especially, we focused on the reusable library for the object-oriented programming environments.

In the climate of increasing calls for academic assessment, the author undertook a study to ascertain availability of original texts and their translations in the academic library. The object of this study is to compare the use frequency of original texts by academic major of users in the university libraries. To achieve this object, the author collected the data stored in 3 Korean university library online systems from September 10th to 30th, 1995 and tested the hypotheses by using the Minitab statistical package. Libraries with multilingual collection and automated systems will find the methodology Presented here Particularly valuable.

This study is supposed to the way to add and enlarge the elements related to educational domain in metadata of school library information system (DLS) by using the concept of learning object which the education information service agencies have adapted. This study is to propose the methods which can be accessed according to the units of learning content in order that they can be applied to the teaching and learning situations, and describe and index the total traits of interior data elements included in the information resources. Thus, the metadata of the existing DLS through the additional elements : , , and was made to access the information resources according to the teaching and learning situations and to accept the concept of interior learning units by means of the element.

In these days, the public library role for the lifelong education is getting enlarger. Thus the study suggested the ground of argument for the necessity that the public library should be in charge of the lifelong education through the relationship between the public library and the lifelong education. Based on this argument, the tendency or trend of the lifelong education, which has been performed overseas and domestically, was researched in the aspects of content, object, connection, basic facility and etc. As the result, the basic data needed to establish the lifelong education system in the library was suggested.

We propose 'the haptic primitive' for haptic rendering without the need to solve complicated parametric equations. To develop 'the haptic primitive', we adopted "the God-Object Method" as a haptic rendering algorithm and applied 'Constructive Solid Geometry' to manage haptic objects. Besides being used in the 'ghost library' of $PHANToMTM^{TM}$ our method can be used as a basic component for developing tools and libraries that aim to simplify haptic modeling. It can also be applied to tactile display modules and temporal display modules. Ultimately it can be developed into a one-stop haptic modeling tool that enables the user to more conveniently create a tangible CAD systems or a tangible e-ommerce system.

A new PC-based Engine Control system (ECS) is developed using an object oriented programming method. This system provides more convenient environment for engine tests, easier user interface and extended functions. A Windows-based ECS software is developed with class, and the class structure is built on encapsulation and abstraction. The closed-loop engine control scheme can be easily constructed by using dynamic link library and multitasking. This means that a user can perform desired experiments without clear knowledge of the hardware structure of the ECS. Also this system allows a user to individually control the ignition and fuel injection for each cylinder in a simple manner such as through a keyboard/mouse or in a real-time operation from a closed-loop control program.

A study on agricultural automation became more important. In Korea, sweet persimmon farmers spend a lot of time and effort on classifying profitable persimmons. In this paper, we propose and implement an efficient grading algorithm for persimmons before shipment. We gathered more than 1,750 images of persimmons, and the images were graded and labeled for classifications purpose. Our main algorithm is based on EfficientDet object detection model but we implemented more exquisite method for better classification performance. In order to improve the precision of classification, we adopted a machine learning algorithm, which was proposed by PyCaret machine learning workflow generation library. Finally we acquired an improved classification model with the accuracy score of 81%.

To get social recognition and the basis of development of public libraries in the 21st century, the knowledge information age, Public libraries must recognize their social role clearly and perform it effectively. For performance of advisable social role of public libraries, this study proposed that 1) establishment Library's Bill of Rights, 2) abolition of the function of‘reading room’of libraries, 3) reform of the assessment system and introduction of certification system for improvement in service quality, 4) an epoch-making improvement of library collections.
